Product Description:

The FC-102P18KT4P21H2XGXXXXSXXXXAXBXCXXXXDX is a Danfoss variable frequency drive in the VLT FC 102 HVAC Drives series. It is installed between the mains supply and an induction motor, where it adjusts output frequency and voltage to match the speed demand of fans, pumps, and compressors in building systems. In HVAC service, that control method allows the motor to run only as fast as the process requires instead of staying at full speed. This helps reduce unnecessary energy use, limits mechanical wear during normal operation, and supports stable airflow or water-flow regulation when the drive is linked to a building-management system or PLC.

The inverter delivers 18.5 kW of continuous output, which is approximately 25 HP. It operates from a 380–480 VAC supply on three-phase power networks, making it suitable for common commercial and industrial HVAC electrical systems. An integrated RFI filter helps reduce conducted emissions on the supply lines, and the enclosure has an IP21 / Type 1 backplate rating for installation in ordinary indoor electrical rooms. The unit is supplied in a base electrical configuration without added option modules, which keeps the wiring layout focused on standard power, motor, and control connections.

Operator interaction is provided through a graphical local control panel, which supports text-based navigation and routine parameter access at the drive. The display uses the standard language pack, so menus are presented through familiar text and icon screens. The mechanical layout uses standard cable entries for straightforward gland installation, and it is built on a Frame B and C backplate for open drive back arrangement that allows the rear heat sink to vent into the cabinet plenum. This layout helps manage heat inside the enclosure while keeping the front of the unit accessible for status checks and local adjustments. The drive fits cleanly into HVAC control panels where predictable airflow and organized cable routing are important.
